Q:

# 50% of babies are born female. Olive wants to find he probability that 20 or more of the 50 babies are born today were female. If we use a double-sided coin and assign heads as females and tails as males, what is the best way to perform this simulationA. Keep track of the number of heads flipped in 50 flips . These represent the number of females born todayB. Keep track of the number of heads flipped in 100 flips. These represent the number of females born todayC. Keep track of the number of heads flipped in 50 flips. These represent the number of females born today. Repeat this 5 timesD.Keep track of the number of heads flipped in 50 flips. These represent the number of females born today. Repeat this 200 times

Accepted Solution

A:
Answer:A. Keep track of the number of heads flipped in 50 flips. These represent the number of females born today.Step-by-step explanation:Remember: we are performing a simulation.A double-sided fair coin has a 50% probability of landing heads and a 50% probability of landing tails; therefore, it is a good choice when simulating our scenario.Since we are performing a simulation, flipping the double-sided coin 50 times, results in the outcomes similar to 50 babies born today; therefore, keeping track of the number of heads flipped in 50 flips represents the number of females born today. Doing something else like flipping the coin 100 times and keeping track of the heads gives us the number of females born when 100 babies are born, NOT when 50 babies are born. Therefore, choice A is correct.
